Application of manure has been used to increase the nitrogen status of many arid and semi-arid agricultural soils, however, organic nitrogen contained in animal manures must be mineralized prior to utilization by crops. Nitrogen mineralization is, like other biological processes, affected by soil water status. This can be due to the direct influence of soil moisture and/or salt interactions on the nitrogen dynamics. It is critical to understand the interactive effects of salt and water on nitrogen in soils amended with organic fertilizer. Such knowledge may be used for improving and quantifyin

Abstract:
Abstract Traditional tank lining coatings are costly, have high VOC content and generally require a high film thickness of multiple coats. This paper presents the results of testing a new type of coating system applied to the inside of tanks, exposed to corrosive environments. This new coating system has been extensively tested in the laboratory and field applications. The field applications include several holding tanks, where the products for storage vary from hydrocarbon to high salinity solutions. The coating system consists of a low VOC rust converting water based primer and a high solids

Full text
Abstract:
Abstract Iron is soluble in reservoir waters which have high salinity and high hydrogen sulfide content. As the well produces, iron sulfide is precipitated due to the drop in pressure with the resultant increase in pH. The crystallites attach to the lower portion of the tubing, where either bimetallic or crevice corrosion occur beneath the crystallites. Gas condensate wells will deposit a high molecular weight material, such as asphaltene, on the iron sulfide crystallites as they deposit. Under these conditions the scale cannot be removed by hydrochloric acid, surfactants, or chelating agents.

Abstract:
Abstract Aluminum-based alloys are widely used in sea water as galvanic anodes. Conversely, their use in soil is not recommended because they tend to passivate when chloride content is low. However, there are chloride contaminated soil where the use of aluminum anodes may be of interest. The aim of this research is to evaluate the effectiveness of aluminum galvanic anodes in low salinity solutions at different chloride/sulfate ratios. The research followed two phases: electrochemical characterization of anodes through potentiodynamic and free corrosion potential tests in solution with differen

Abstract:
Abstract This industrial case study highlights measures that were undertaken to maintain the structural integrity of a subsea tree in the North Sea. The formation water produced along with the hydrocarbons contained more than 220,000 mg/L of chloride ions, rendering the corrosion inhibitor that was used ineffective. For the corrosion inhibitor to be effective, the chloride content could not exceed 135,000 mg/L. To address this issue, seawater, or washwater, was mixed with the production water in a low-alloy steel flowline to lower fluid salinity, enabling the corrosion inhibitor to function. H

Abstract:
Abstract Water reinjection wells improve the oil recovery and normally consist of tubing made mainly in Super Duplex Stainless Steel (SDSS) with a minimum PREN of 40. Experimental data have supported the susceptibility of these steels to localized corrosion, with dissolved oxygen content (DOC), salinity, temperature and pH as main factors for the corrosion process. A study was carried out exposing Super Martensitic Stainless Steel (SMSS), Duplex and Super Duplex Stainless Steel (DSS and SDSS) to seawater (DOC: 500ppb; Cl-: 24,000ppm) and produced water (DOC: 10/50ppb; Cl-: 165,000ppm) for 15 d

Abstract:
Standard salinity management theory, derived from blending thermodynamic and semi- empirical considerations leads to an erroneous perception regarding compensative interaction among salinity stress factors. The current approach treats matric and osmotic components of soil water potential separately and then combines their effects to compute overall response. With deficit water a severe yield decrease is expected under high salinity, yet little or no reduction is predicted for excess irrigation, irrespective of salinity level. Similarly, considerations of competition between chloride and nitrat

The objectives that were outlined in our original proposal have largely been achieved or will be so by the end of the project in February 1995 with one exception; that of mapping cold tolerance loci based on the segregation of tolerance in the BC1 progeny population. Briefly, our goals were to 1) construct a densely populated linkage map of the citrus genome: 2) map loci important in cold and/or salt stress tolerance; and 3) characterize the expression of genes responsive to cold land salt stress.

Abstract:
The tomato, a profitable vegetable crop in both the USA and Israel, has benefited significantly from intensive breeding efforts in both countries, and elsewhere (esp. Holland). : Modem hybrids are highly prolific and resistant to a variety of major pests. They produce attractive, firm fruit for both processing and fresh-marketing. In all cases, however, reduction in flavor and aroma have occurred concomitantly with the increase in yield. Sugars-acids ratio dominate fruit taste, whereas aroma volatiles (potent at minute ppb and ppt levels) contribute to the total characteristic tomato flavor. A

The project exploits the use of Artificial Neural Networks (ANN) to describe infiltration, water, and solute distribution in the soil during irrigation. It provides a method of simulating water and solute movement in the subsurface which, in principle, is different and has some advantages over the more common approach of numerical modeling of flow and transport equations. The five objectives were (i) Numerically develop a database for the prediction of water and solute distribution for irrigation; (ii) Develop predictive models using ANN; (iii) Develop an experimental (laboratory) database of
